I just bought a military sleeping bag off of eBay. It is two piece but doesn't have the bivvy. Supposedly these things are good to minus thirty.

Anyone ever use one?

I will be hunting in the Gila national forest and the lows will be in the twenties. I am a little cold natured.

Thoughts?

CD,

Two pieces, one black one green??? Used together they will definitely keep you warm. Neat thing about the two pieces, you may not need both of them at any given time. I've used just the green one when it was warm to cool, just the black when it went down beyond cool. Never had to use both of them together though, but I know what they're rated for.

Spent some time in the great big kitty litter box and that's what I was issued to keep me warm at night.
